Hi,
A l10n NMU will happen on pppconfig pretty soon.
A round of translation updates is being launched to give all translators a chance to get their translations in for that package.
Please send the updated file as a wishlist bug against the package.
(there are many translations for this package as it was listed in D-I statistics in the past)
The deadline for receiving the updated translation is Sunday, April 11, 2010.
Thanks,
